Piinah it is 1800 feet, and the peaks of the chain attain au
elevation of 4-5000 feet, hut they are separated by great de-
pressions. The table-land of the Dekhan forms the watershed
between ,the basins of the Kistna and the Godavery, and has
an average elevation of from 1800 to 2000 feet, with an un-
dulating surface, but no mountains rising much above the
mean level. Hyderabad is 1672 feet, the Cantonment of Se~
canderabad, close by, 1837 feet, and a hill near, 2017 feet
above the level of the sea. The valley of the Godavery is of
course considerably lower. The surface of the table-land,
which is generally open, with little forest, but much low
jungle, is at one season richly cultivated, but during the re-
mainder of the year extremely arid and burnt up.
The abrupt escarpment of the western Ghats condenses so
much of the moisture of the south-west monsoon, that the
summer rains iu the Dekhan are very moderate in amount,
arcl the north-east monsoon is so much a land-wind, that but
little rain falls during the cold season. The rain-fall at Hy-
derabad and Jaulnah averages about 43 inches; at Satara
(2300 feet) it is 36 inches. The mean temperature of Punah
is 77, and the rain-fall 24 inches. This is the average rain-
fall throughout the north-western part of the district, close to
the crest of the Ghats, but the amount is greater to the east-
ward.
Along the crest of the Ghats, the hilly tract known as the
Mawal possesses a vct*y different climate and aspect from the
remainder of the Dekluux, bearing more resemblance to the
Concan. This is due to its greater humidity; the depres-
sions of the watershed, here as elsewhere, allowing the mois-
ture-laden wind to pass to the eastern part of the chain for a
considerable distance. In this district the surface is peren-
nially green, and the vegetr Aon much more luxuriant than
further east. In the w.est' .n parts of the district of Belgaum
this tract is especially marked, as the depression of the moun-
tains is there greater than elsewhere. At Belgaum the rain-
fall is 50 inches, and at Dharwar 39 inches. These numbers,
